WTF do you do with that much pasta, candy, ketchup, and sports drinks? How do you possibly consume all that? I know that stuff keeps for awhile, but that's ridiculous.
my dad's devoted the entire basement of their house to grocery storage.
when I was still living there, the basement had a play room (that I took over as my bedroom), a workshop where the previous owner had all of his tools, a laundry/bathroom, and a small pantry.
pretty early on, the workshop got utilized for grocery storage... after I moved out was when things really went off the rails, though. he had my old bedroom gutted and installed shelves around the entire room to store groceries on.
I don't know what they'll do if they ever have to sell that house, they turned a perfectly serviceable playroom/third bedroom into this weird walk-in, private grocery store.
they've also got 2 full-sized refrigerators (in addition to the one in the kitchen) and 2 chest freezers for storage.
my mom is a clean freak, thank god, so they don't have to worry about pests/bugs, but it's still kinda gross because my dad is not good about cycling out expired products. the last time I was over there and needed a bottle of ketchup, I ended up going through about 5 expired bottles before I found one that was still good.
